METAL wINnow-scnnnlv.

l To all whom t may concern:

Be it known that I, ALFRED M. LANE, a citizen of the UnitedStates, and a resident of the city of St. Louis and State of Mis souri, have invented a new and useful Innc provement in Metal Window-Screens, of which the following is a specification.

y invention relates to metallic window window screens have been made with metal frames; but they have been subject to divers disadvantages. The more common disadvantages are that the frames are more or less flimsy in construction or else they are unnecessarily expensive; many of them are of more or less unsightly appearance; and usually it is quite difficult screens. Heretofore,

or impracticable to replace the wire cloth.

- showing a special The object of the present invention is to overcome these disadvantages and to produce a screen of neat appearance, adapted for economic manufacture, of great strength and rigidity and well adapted for repair and replacement of parts. It consists in the parts and in the combinations of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification, and wherein like numerals refer to like parts wherever they occur,

members A and outside members B. detachably secured together, preferably by screws i3, with the wire fabric or meshwork 14; lnterloclred or engaged between them. Preferably the frame members are straight pieces mitered at their ends and held together by means of corner pieces 15 provided for the purpose.

The frame members are preferably of the cross section illustrated in Figs. 2 and 3. In the construction illustrated in said gures, the inside frame member A is a strip of sheet-metal bent endwise in such manner as to form a hollow boxing. For this purpose, the longitudinal marginal portion of said strip is folded back to lie Hatwise against the adjacent portion of the strip and thereby stiffen it and adapt it to constitute the outer end wall 16 of the boxing. The inner side wall 17 of the boxing, constituting the inner face of the frame, is a substantially plane surface disposed more or less perpen- The third or inner end wall 18 of the boxing is substantially perpendicular to the inner side wall thereof and is preferably slightly nar rower than the outer end wall. The fourth wall 19 or outer face of the boxing is of irregular form especially designed to cooperate with the other parts of the device.

lNhere the fourth side, being the outer face a convex curve that is continued inwardly substantially parallel with said third side and thence is continued in a more or less semi-circular curve, thus forming a hook portion 20 at the inner end wall of the frame and a socket or groove 21 adjoininY the same. F rom this socket, the said fourtii side of the boxing extends for a distance substantialiy parallel with said second side and thence is formed into a terminal loop 22 of proper length to bear against the corner portions of the first and second walls of the boxing and constitute a brace. The end portion of the terminal loop is spaced from the first or outer end wall of the boxing to form a groove or recess 23 for cooperation with the outer cooperating member of the frame.

y reason of the section above described, not Vonly is the main body portion of the boxing hollow, but suiiicient space is left wherein they are between said fourth side and the second and third sides to'receive reinforcing member 15 hereinafter described. In practice, it is desirable to solder the terminal loop to the outer end wall of the boxing at their line of contact, as illustrated at 24. The resulting boxing is o great strength and furnishes two longitudinal grooves or recesses in the outer face, together with such resiliency as may be desirable therefor; and at the'same time, it affords a convenient way of neatly and tifrhtly securing the parts together.

e wire cloth 14 or other suitable meshwork has` grooves or hollow ribs rolled orv otherwise formed adjacent `to its margins, preferably by rolling the same prior to assembling.y rIhese marginal ribs in the wire cloth are about the same width but preferably slightly shallower than the grooves in the boxing into which they are fitted and held by means of ribs 25 on the outer members of the frame.

Each of the outer frame members B comprises a strip of. sheet-metal folded flatwise to form a double thickness. Near the inner edge of the outer frame member, its inner ply is bent to form a rib 25 in position to enter and coperate with the inner groove of the boxing; while the outer marginal portion of said outer frame member is bent inwardly to form a rib 26 in position to engage and coperate with the outer groove or recess 23 provided therefor in said oxing. Preferably the outer ply of said outer member is formed into a loop 27 that completely incloses the terminal flange of the inner ply and the parts are soldered together as indicated at 28 to make the outer member stiff and strong.

The inner and outer members A and B of the frame are preferably secured` together by means of screws 13'that pass through countersunk holes formed therefor in the outer member and punched or threaded holes in the middle portion of the outer side' of the boxing. The inner ends of the screws are concealed within the boxing, while the exposed heads of the screws lie flush with the outer surface of the frame.

At the corners, the frame members are by means of corner brackets joined together members 15. These corner or reinforcing brackets are preferably -made of heavysheet-metal forged or otherwise formed into the sectional shape illustrated in Fig. 2; that is, of a shape to fit' in the hollow of the boxing and follow the inner surface of the outer side wall thereof. Threaded holes 29 are formed through said corner brackets to receive threaded screws 30 that pass through countersunk holes in the outer frame member and through the outer wall of the boxing. Preferably, the surface of the corner bracket is the corner bracket orv with its counterpart grooved ,or depressed around the threaded hole for the purpose of receiving solder intended to hold the parts together as indicated at 31. Likewise, solder is preferably used in the angle between` the inner lip or flange of the corner bracket and the b ottom wall of the socket or inner groove 1n thev boxing.

It is noted that, when the parts are secured together, the frame presents a very neat appearance and is very sti and strong. As the parts in contact with the wire cloth have their -f corners rounded, there 1s very llittle danger of tearing the cloth; and when the cloth requires replacement, it is only necessary to disengage the screws and separate the frame members, whereupon the old cloth can be removed and replaced with a new cloth, after which the frame members can be reassembled and secured.

In the modification illustra-ted inv Fig. 3, Y

a hinge or mounting member 32 is secured to the frame. This hinge or mounting member comprises a sheet of metal rebent to form a loop that straddles the doubled edge of the outer wall of the boxing, the inner edge of said loop being flanged in position for the outer rib 26 of the outer frame member to bear against, and the outer marginal portion of said loop being formed into an eye 33 or otherwise adapted for coperation mounting member.

AIn the modification illustrated in Fig. 4,

the inner wall of the boxing is extended beond the outer end wall thereof `to form a` In the modification illustrated in Fig. 5.-

both guide ribs 34a and 35a are formed 1ntegral with the boxing. It is noted that, in this design, the outer vframe member terminates Hush with the inner face of the inner rib, whereas in the other designs, the inner margin of said outer frame member extends inwardly beyond said rib and serves the twofold purpose of clamping the wire cloth and making a neater appearance.

-In the modification illustrated in Fig. 6, the inner rib of the outer frame member is replaced with a groove 36 adapted to receive a locking bar or member 37 that, in a general way7 serves the purpose of the guide rib.

Obviously, the construction hereinbefore formed into a socket that' described admit-s of considerable change and I do not wish to be restricted to the details described.
